Located in Eureka, Missouri—a suburb of St. Louis—Mid America Adventure is a classic Midwestern amusement destination. Originally conceived in the 1960s by Angus G. Wynne and opened on June 5, 1971, as Six Flags Over Mid-America, the park operates across a 323-acre property. In 2026, EPR Properties purchased the site and hired Enchanted Parks to manage operations, officially renaming the park to Mid America Adventure while maintaining its signature family entertainment experience for travelers visiting the St. Louis region.
The park layout follows a classic Duell loop design, organizing your visit through eight distinct themed areas. You can wander through 1904 World's Fair, Gateway to the West, Chouteau's Market, Studio Backlot, DC Comics Plaza, Britannia, Illinois, and Bugs Bunny National Park. Every section reflects a unique theme, from historic Midwestern history and colonial trading posts to Hollywood movie backlots, medieval British legends, and beloved animated characters, offering broad visual variety as you navigate around the continuous central loop.
Whether you are seeking thrills, family entertainment, or water fun, Mid America Adventure offers diverse experiences. Theme park guests can enjoy iconic attractions such as Justice League: Battle for Metropolis and Mr. Freeze: Reverse Blast in the DC Comics Plaza, alongside daily live theater shows included with park admission. Adjacent to the main park lies the 12-acre Hurricane Harbor water park. Operating from April through November, the park also hosts its famous autumn Fright Fest event, making it ideal for day trips and family stopovers.
